Abstract
An LED string control system includes an LED string and a control module. The control module provides a first voltage level according to a first digital logic of a light command, and provides a second voltage level according to a second digital logic of the light command to form a control signal. Based on consecutive first digital logics and/or second digital logics of the light command, the control module adjusts a voltage level of the control signal to a third voltage level as a distinction voltage level for distinguishing two consecutive first digital logics and/or two consecutive second digital logics.
